Subject: [PATCH] gnu: linux-libre: enable hidraw by default

From: Tom Fitzhenry <[email-masked]>

* gnu/packages/linux.scm (%default-extra-linux-options): Enable CONFIG_HIDRAW.

hidraw is needed to create /dev/hidraw* devices, commonly used for U2F
devices, e.g. via libu2f-host.

CONFIG_HIDRAW is not enabled in the mainline arm64 defconfig, but is enabled
on:
* the mainline x86_64 defconfig
* gnu/packages/aux-files/linux-libre/*arm64.conf

HIDRAW's Kconfig documentation advises "If unsure, say Y."[0]

Tested by compiling and running linux-libre-arm64-generic, and observing that
/dev/hidraw* devices are created, and SSH-via-U2F now works.

0. Linux kernel, drivers/hid/Kconfig
